A linear bis secondary dialkylammonium ion-containing scaffold - based upon an anthracenyl core-has been synthesized. It has been demonstrated that it is possible to dock either one or two dibenzo[24]crown-8 (DB24C8) macrocycles onto this scaffold to afford either a [2]-or [3]pseudorotaxane, respectively. In solution, the association constants for the formation of each of these species has been quantified by employing ¹H NMR spectroscopy, and both species survive in the "gas phase" as evidenced by FAB mass spectrometry. Additionally, the X-ray crystal superstructure of the [3]pseudorotaxane has been determined.
